I have been eyeing these online for a while and finally decided to get them. They are so comfortable and gorgeous. I am usually a 38.5 in Lanvin flats, so I ordered these in 38.5 and they fit like a glove.
As a "shoe person" I've often been a bit surprised that there isn't more activity in this forum on tPF - I try to participate where I can but sometimes it seems that all the threads have a "recent post" from ME on them when you're viewing the index, and that can seem a little, uh, excessive?
For the record: Your new sandals are awesome!!! I don't own any Lanvin but I've eyed them for ages, and those slides are very practical and look really comfortable! I'm glad you posted.
